Space‐ and Time‐Resolved Combined DRIFT and Raman Spectroscopy: Monitoring Dynamic Surface and Bulk Processes during NO_<i>x</i> Storage Reduction

Abstract

What, where, when: A combination of both surface-sensitive (diffuse reflectance infrared Fourier transform spectroscopy, DRIFTS) and bulk-sensitive (Raman spectroscopy) detection at different catalyst-bed positions is shown to be a powerful tool to facilitate deeper understanding of complex dynamic surface and bulk processes, which occur widely in heterogeneous catalysis.
